The ideology of intelligent tutoring systems

After approximately four decades of evolution, the attempt of using Intelligent Tutoring Systems (ITS) as extracurricular assistances is now widely accepted. As a rapid growing subarea of expert systems, their accomplishments are remarkable. During the exploration of making virtual tutors more humanlike, researchers have made a great deal of efforts on the investigation of further in-depth rationales and technologies such as tutoring paradigms, student modeling, instruction modeling, adaptive curriculum planning, and user interfaces. In this paper, I compiled some literatures on those essential issues and concluded the future of ITS at the end. © 2010 ACM.
